SPl NDLE-SUPPORT FOR SPINNING-SPINDLES.

SPECIFICATION forming part Of Letters Patent NO. 416,286, dated December 3, 1889.

Application filed July 24,1889. Serial No. 318,490. (No model.)

To all whom it may concern:

Be it known that I, STOCKTON BATES, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Spindle- Supports for Spinning-Machinesg and I do hereby declare the following to be a full, clear, 1 and exact description of the invention, such as will enable others skilled in the art to My invention relates especially to spindlesupports adapted for use with single-rail spinning-frames wherein the spindles aredriven by whirls arranged below the rail, and the supports are respectively provided with a double-armed yoke for the reception of the whirl, and respectively with ,a lower continuous bearing and oil-well extension pendent from the yoke, as instanced in Letters Patent No. 138,929; and my said invention consists in a spindle-support comprising upper and lower separately-constructed sections, the upper section being formed with an upper tubular screw-threaded portion for an upper bearing, on which a confining-nut is screwed above the rail, and said portion unit-1 ing with an annular shoulder at the bottom; of the rail, said shoulder having two diametrically-opposite segmental yoke-arms extending outwardly'and downwardly from it, which arms [are united by an annular internally screw-threaded-coupling base portion, and the lower section being formed with a continuous tubular lower bearing-chamber and oilwell having an annular screw-threaded upper coupling portion,'at the base of which an annular shoulder is formed, and in the lower end of the lower section a foot-bearing is seated, all as will be hereinafter described and specifically claimed. 7

By my improvement a very rigid, light, and

divisible spindle support or bolster is produced, the spindle is sustained centrally on a two sides by the yoke-arms, and all tendency to get out of true line by reason of undue one: sided strain, on account of being supported by only one yoke-arm, is overcome; and while this is the case the lower section is removable by simply unscrewing it from the upper section, and when it is removed the spindle and whirl can be removed downward through the yoke without disturbing the upper section of the spindle-support. The construction of said lower section is also such that the oil well or chamber affords room for the revolution of the lower part of the spindle, even though said portion of the spindle may have become crooked.

My invention is illustrated in the accompanying drawings, which show a vertical central section through the spindle-support and bolster-rail, the spindle and whirl being in elevation, and by 'a perspective detail view, said views being designated as figures 1 and 2.

' The letter A represents a bolster-rail; B, a spindle; O, the upper section, and D the lower section, of my spindle-support.

The bolster-rail A is of plain prismatic shape, and its upper and lower surfaces are exactly parallel and perfectly plain, so as to insure parallelism to the axes of the spindles and facilitate the equidistant and lateral adjustment of the spindle-supports, as will be hereinafter shown.

The spindle B is of ordinary construction, having tapering top and foot portions and a cylindrical intermediate portion.

The upper section 0 of the spindle-support consists of atubular portion 0 provided at its upper end with a screw-thread c and nut c and terminating below in a horizontal annular shoulder c which shoulder is the upward termination of a disk formation 0 below. On two opposite sides of disk 0 two yoke-arms c unite with said disk, and their lower ends unite with an annular base formation 0 having a circular opening c with an inner screw-thread c therein, and an external horizontal shoulder a thereon. Into the threaded opening 0 an upper screw-threaded portion d of the lower section D is secured by a matching screw-thread d and by a horizontal shoulder d, forming a perfectj oint with shoulder 0 The lower body portion 01 of the section D is preferably tapered, and is hollow to such an extent as to form a continuous closed oil-chamber d around nearly the entire lower portion of the spindle. A removable bushing 12 is inserted into the tubular portion 0 and serves as an upper spindle-bearing. A similar bushing 61 is inserted in the top portion of section D and serves as a lower lateral spindle-bearing,while a foot or step bearing (Z for the vertical support of the spindle is insorted in the bottom portion of said section 1). These inserted bearings may be of any equivalent construction to that shown, or they may be omitted and equivalent bearings formed on sections 0 and D without departin g from the principle of my invention.

The spindle ii is provided with a whirl Z), which is placed between the upper and lower spindle-bearings in the yoke c 0", so as to be inclosed on two sides. The openings a for the reception of the tubular portions 0 in the bolster-rail A are cast,instead of being bored, of such diameter as to permit the support or bolster to be moved about therein for the purpose of centralizing and spacing or adjusting the spindle-supports properly on the rail. The facility of this adjustment depends upon the specific construction of the upper sections of the spindlesupports, the same being provided respectively with a dowel-pin 0 inserted into the shoulder c in line with the yoke-arms 0* at a given distance from the axis of the spindlesupport. It is easily seen that dowel-pins set in holes equidistantly bored in the bolster-rail and arranged in the center line of the bolster-rail will serve to hold the spindle-supports and spindles equidistant on the rail, so that they can be aligned or adjusted transversely without losing their equal distance while being moved upon or around said dowel-pins for such purpose. After being thus adjusted and secured by means of the nuts 0 the sections 0 will not be detached from the rail unless found unsuited for longer service; and when an exchange of sections 0 is necessary, the same can be easily and speedily effected, as they are all constructed precisely alike, and the dowel-pins serve as indices for their replacement. The lower portion of the spindle is completely housed by the lower section D, and only held by the bearing d" below the whirl and by the step-bearin g, and thus nearly its whole tapered lower portion is free from contact with the inner walls of the said section D. This is done in order to facilitate the righting or adj ustin g of the spindle, which from any cause during its operation may cease to run truly vertical above the upper bearings. In such case the lower tapered portion of the spindle is so shaped by bending as to throw the upper portion of the spindle in line again. The lower portion of the spindle, although not true with the upper portion after being thus bent, will not be interfered with in its easy revolutions, because said bent portion will move in a free space (1, between bearings d" and d, and the long leverage of the spindle below the cylindrical bearings Z) and d insures a steady motion of the same. I extend the section D and the step-bearing therein considerably down below said cylindrical bearings and place the two cylindrical bearings as close together as the whirl and the space necessary for its manipulation will permit, in order to prevent any yielding of the spindle between the said cylindrical bearings, and thus make that portion of the spin- (lle the fulcrum between the two ends. In order to remove the spindle, the lower section D is unscrewed and the spindle pulled down out of its bearing and out of the yoke without removing the whirl, which is of smaller diameter than the opening 0 The spindle is reinserted in the bolster-bearing from below, and finally secured by sliding up the section D upon it and fastening the same by screwing it into the thread 0" of the section until the shoulders c and (Z are firmly clamped together, by which operation the sections 0 and D are again perfectly aligned without any care on the part of the operator.

\Vhile it is very important to have the support divisible, as hereinbefore described, it is also essentially necessary to have on the upper section the described two-armed yoke in connection with the long continuous oil-well and bearing portion of the lower section D of spindle-support, in order to avoid a deflection of said portion and the throwing of the spindle-bearing out of a vertical line with the spindle. Were a single bracket-arm used with the long continuous oil-well and bearing therein, the leverage strain resulting from the great length of leverage afforded by the lower part of the spindle below the bearing would be liable to force the bearing-step of said bracket to one side, and owing to the great distance between the bearings 61* (Z the slightest deflection of the bracket near the bearing cl" would become very considerable at the bearing (1 and cause the foot-bearing d to stand out of line with the other bearing (1 and thus produce bind upon the spindle. \Vhen single-arm brackets are used, the downward extension below the bracket is usually left oif, and the disadvantage of the lev- 11o erage resulting from such extension is avoided, but all the benefits arising from the use of such extension of the bearing and the lengthening of the spindle are lost. My divisible spindle-support having a double-armed yoke admits of the downward removal of the spindle with the whirl attached to it, and at the same time avoids the liability of lateral deflection of the foot-bearing.

What I claim is- 1. A spindle-support consisting of an upper section 0 and a lower section D, the upper section comprising a tubular portion attachable to a bolster-rail, and a two-armed yoke adapted to contain the whirl below the rail, and the lower section comprising a spindlebearing below the whirl, an oil-space below said bearing, and a step-bearin g at the bottom of said oil-space, substantially as described.

2. A spindle-support consisting of upper and lower sections C D, the upper section 0 comprising an upper tubular screw-threaded portion for an upper bearing, on which a confining-nut is screwed above the rail, said portwo diametrically-opposite segmental yoke arms extending outwardly and downwardly from it, which arms are united by an internally-screw-threaded coupling ,base portion, and the lower section D containing tubular lower bearing for the spindle and a step and an oil-well and formed with an annular screwthreaded upper coupling portion, at the base of which an annular shoulder is formed, substantially as described.

3. In a spindle-support, the contin uouslower section provided with a coupling-screw and a shoulder at its top and having a bearing near its top and a hearing at its foot and chambered between said bearings, so as to form a lubricating-chamber or oil-well, which chamber is of such diameter that it permits of the lower portion of the spindle revolving, even though it has been crooked, without coming in contact with the wall of the chamber, in

combination with the upper section 0, having two yoke-arms o ,'a screw-threaded tubular portion 0 a shoulder 0 for bearingagainst the rail, and an annular internally-screwthreaded and externally-shouldered base portion 0 substantially as described.

4. The means herein described, whereby the spindle is truly held centered and supported, consisting of the bearing-section O and bearing-section D, said sections 0 and D being united by screw-threads c d and shoulders c d below the rail and fastened to said rail by means of said shoulder a and nut c, the rail with a hole of larger diameter than the tubular portion of section 0, and dowel-pin 0 substantially as described.

In testimony whereof I hereunto affix my signature in presence of two witnesses.
